Answer:
MAC Addresses (Destination and Source MAC address)
Explanation:
A switch has 3 primary functions:
- Forward frames
- Learn addresses
- Avoid loops
An Ethernet frame has the header, data and trailer and there are two specific fields in the header that helps the switch to know where to send data in future transmissions.
- destination MAC address
- source MAC address
every Ethernet frame has this and when the frame hits a switch or any device, any device can look at it ( an Ethernet frame ) and know where it is suppose to go and where it came from.
Every switch has a MAC address table where it stores MAC addresses of different computers on the network.
Example:
When a PC1 sends a frame to PC2 through a switch, the switch looks at the header of the Ethernet frame for the source mac address and adds the source MAC address to its MAC address table and also the port that it came through.
simply put:
A switch looks at the source MAC address to see if it knows it already, if it does. Great! no need to add it again to it's address table.
If it doesn't, it adds it's source address and the port that the frame came from.
This basically how the switch populates its MAC address table.

The statement that completes the query is: bytes / 1000 AS kilobytes
<h3>SQL (Structured Query Language)</h3>
This is the language that is used to retrieve, update, and store data in the database.
<h3>Columns</h3>
From the question, we have the following table columns
- track_id
- track_name (name of the music track)
- composer
- bytes (digital storage size of the music track
To retrieve data from the bytes column, we make use of:
SELECT bytes ......
From the question, we understand that this column should be divided by 1000, and the AS command should be used.
So, the query becomes
SELECT bytes / 1000 AS kilobytes .....
Hence, the statement that completes the query is: bytes / 1000 AS kilobytes

I’d say monthly. It probably wouldn’t kill you to do it every three months though.
